The addition of carbamoyl anions derivedfrom N,N-disubstituted formamides and LDA to N-tert-butyl nitrones is described. The reaction was demonstrated with a variety of formamides and nitrones and provided a direct route to α-(N-hydroxy)amino amides. The use of a tert-leucinol derivedchiralauxiliary on the nitrone provided products in good diastereoselectivity. Derivatization of the products by
